So my front pinion seal was slowly leaking 2 years ago...so I removed and replaced it. Last night I was changing the diff fluid and when I was pouring the fluid down the breather tube I gave the bottle a squeeze!! I could hear air blowing as I squeezed the container. Did it a few more times looking and listening. Found that the air and fluid was coming out around the seal again!! Anyone else have this happen?? Do I need a new seal?? Or maybe a new pinion bearing and seal? I’m a little stumped

any help would be great thanks
